Me neither.

That sounds plausible. Thanks!

Well, the discussion at this bug report has indeed mentioned quite a few
other font rendering aspects. We would need a font expert to sort it.

But as regards the fonts-ubuntu bug task we *might* now have the answer,
i.e. not a bug.

@mrvanes: What do you think? Do we have a reasonable explanation with
respect to fonts-ubuntu and hinting? If not, you may want to chime in at
the upstream issue which Sebastien pointed at.

  Font hinting broken on 23.04

Status in fonts-ubuntu package in Ubuntu:

Bug description:
  Just upgraded my laptops to Kubuntu 23.04 Lunar Lobster and hinting
  for all non-commercial fonts seems broken. I used to have decent if
  not perfect hinting on Ubuntu and Ubuntu Mono font, but now the only
  fonts that still hint correctly are Microsoft's Verdana and Tahoma
  etc. Not sure whether the devide is exactly along this line, but it
  stands out.

  Tried regenerating font cache (fc-cache -rv) but that didn't help.
